Description:

Hose wire is also called steel wire for hose reinforcement, brass-plated steel wire, rubber tube wire, or brass rubber tube wire. It is used as the reinforcement layer of the rubber hose. These high-pressure rubber hoses could sustain high pressure and high impact, and they can be used for machinery, aviation, ocean, oil drilling and some other special occasions. The hose reinforcement steel wire is carried out in line with GB/T 11182-2006 Standard, We mainly produce hose reinforcement steel wire with the diameter of 0.20mm to 0.8mm. Other specifications according to customers' requirements are also available.The surface of steel wire for hose reinforcement is plated a layer of uniform copper zinc alloy. The ratio of copper to zinc is 68±4%:32±4%. The tensile strength is mainly classified as three grades: 2150-2450, 2450-2750, 2750-3050, 3050-3350N/mm2, the torsion value is more than 50 times, and knotting strength ratio is more than 58%. The weight of brass coating is heavier than 3.0g/kg. The steel wire has good line shape, the diameter of cast is no less than 120mm, and the helix is no more than 50mm.
